Title: A method for function change of a database
Inventor: NILSSON INGVAR
IPC: G06F17/30
Filed: 1997-02-07
Abstract: The present invention relates to a new database handling protocol for function changing of data from an old database (202) to a new database (204). The protocol solves those problems that occur when large quantities of data shall be converted from one database to another database. The new protocol is divided into different phases. A specification phase involves creating data which specifies the configuration of the new database (204). A declaration phase (A) involves creating conversion directives, writing these directives and inserting the directives into a conversion record storage block (208). A  read-in phase (B) involves reading the conversion directives into an operating system (210). A read-out phase (C) involves reading data from the existing database into the operating system. A conversion phase (D) involves converting data in accordance with the conversion directives. An insertion phase (E) involves inserting converted data into the new database. The read-out, conversion and insertion phases are repeated until the whole of the database has been processed. The latter four phases are handled by the operating system (210). The new database is verified in a verification phase (F) to ascertain that the database is consistent.

Title: Network traffic controller
Inventor: LEWIS DAVID G
IPC: H04L12/24
Filed: 1998-09-10
Abstract: A network traffic control system that generates traffic monitor information by monitoring the network traffic and controls the network traffic based on the traffic  monitor  information.     The  network  traffic monitoring system includes a network traffic monitor and a  network  traffic  controller. The  network  traffic monitor  determines   information  such  as  types  of communication,  communicating partners,  and geographical locations  of  the  communicating partners.  The  network traffic   controller  processes   the   traffic  monitor information.   Thus, the traffic network control system reduces the cost of network communication as well as optimizes network performance based on traffic monitor information obtained by the traffic monitor.

Patent CA-2254670-A1 (CA)
Inventor: ALLEMANN MAX
IPC: A47L13/253
Filed: 1998-11-25
Abstract: A cleaning implement (1) wherein the plate-like carrier (2) for a mophead (6) has a centrally located plate-like support (7) which overlaps the upper surfaces of inner portions of two plate-like sections (9, 9a) having outer portions (5) with devices for releasably clamping flaps (33) at the ends of a mophead. Alternatively, the plate-like sections (9, 9a) may be used to secure a mophead (6) having pockets ( 100, 110a). The sections of the carrier (2) are held in a first position (in which their lower surfaces are substantially coplanar and the median portion of the mophead is stretched along the lower surfaces of the sections) by a single locking bolt (14) which is reciprocable in a guide (13) at the upper side of the support (7). The guide (13) defines a pivot axis for the lower end of a handle (4), and the sections (9, 9a) are pivotable about two neighboring axes which are normal to the pivot axis for the handle (4). The locking bolt (14) is selectively releasable into one of two configurations. In a second, collapsed, position, the sections (9, 9a) are substantially confronting. In a third, semi-collapsed, position, the sections (9, 9a) are retained at an angle between the first position and the second position. The locking bolt (14) is automatically locked in the first position when the sections (9, 9a) of the carrier (2) are pivoted back to a coplanar position from either the second position or the third position.

Title: Hydrophilic hot melt adhesive
Inventor: STRELOW DIANE
IPC: C09J11/08
Filed: 1997-06-19
Abstract: Hydrophilic hot melt adhesive compositions suitable for a variety of applications, especially in nonwoven disposable articles, are prepared by blending various adhesive components with a surfactant. The surfactant has a hydrophile-lipophile balance (HLB) number of less than 15, and is incorporated into the composition in an amount such that the resultant adhesive has a contact angle of 75° or less, and preferably less than about 40°. A low contact angle is desirable so that water, urine or other water-based discharges, upon contacting a laminate bound together by the adhesive, wets out rather than beads up resulting in the fluid being directed away from the adhesive and towards an absorbent core of the disposable article.

Title: Linear friction welding process for making wheel rims
Inventor: MAHONEY MURRAY
IPC: B60B21/00
Filed: 1997-08-07
Abstract: A method of forming vehicle wheel rims includes utilizing linear friction welding. A generally planar piece of metal material (20) is placed into a coil position with two ends (22, 24) in abutment. The abutting ends are oscillated or moved, in a generally linear pattern (32), relative to each other to increase the temperature of the metal at each end. After the temperature has been increased sufficiently, without reaching the melting temperature of the metal, the linear motion is stopped.     The ends are then aligned precisely and forced together with an increased axial load (34). After cooling, the two ends are permanently joined together with an essentially defect-free welded joint.

Title: Conforming end stops for a plastic zipper
Inventor: BRYNIARSKI DAVID A
IPC: B65D33/25
Filed: 1997-08-14
Abstract: A plastic bag comprises first and second opposing panels, a reclosable zipper (22), and a sider (32). The first and second opposing panels (12,14) are fixedly connected to each other along a pair of sides (16) and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth (10) formed opposite the bottom. The zipper (22) includes a first track with a first profile (24) and a second track with a second profile (28). The first and second profiles are releasably engageable to each other. The slider (32) is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles (24, 28) are engaged to each other while the slider (32) is in the closed position, and the first and second profiles (24,28) are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider (32) from going past the ends of the zipper and to provide adequate ends strength that resists stresses applied to the profiles during normal use of the bag, end stops (36) in the form of flexible segments severed from a flexible plastic strip, fairly rigid segments severed from an extruded clip profile, or softened plastic material, are applied and secured to opposite ends of the zipper.
